There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to assess the efficacy and safety of treatment with definitive chemoradiotherapy (dCRT) + pembrolizumab (MK-3475) compared to treatment with dCRT + placebo with respect to Event-free Survival (EFS) and Overall Survival (OS) in: - participants whose tumors express Programmed Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10 - participants whose tumors express PD-L1 CPS ≥1 - all participants The primary study hypotheses are that dCRT+ pembrolizumab is better than dCRT + placebo with respect to: - EFS in participants whose tumors express PD-L1 CPS ≥10 - EFS in participants whose tumors express PD-L1 CPS ≥1 - EFS in all participants - OS in participants whose tumors express PD-L1 CPS ≥10 - OS in participants whose tumors express PD-L1 CPS ≥1 - OS in all participants
This study is being conducted to determine whether prophylactic administration of surfactant by the Less Invasive Surfactant Administration (LISA) method reduces the need for mechanical ventilation in the first 72 hours of life when compared to early Continuous Positive Airway Pressure (CPAP) alone.
This Phase 3 study is designed to compare the efficacy and safety of mirvetuximab soravtansine vs. investigator's choice chemotherapy in patients with platinum-resistant high-grade epithelial ovarian cancer, primary peritoneal, or fallopian tube cancer, whose tumors express a high-level of FRα. Patients will be, in the opinion of the Investigator, appropriate for single-agent therapy for their next line of therapy. Folate receptor alpha (FRα) positivity will be defined by the Ventana FOLR1 (FOLR1-2.1) CDx assay.
Background: Drugs known as poly-adenosine diphosphate ribose polymerase (PARP) inhibitors are known to help stop tumor growth in patients with breast, ovarian cancers and many other cancers including prostate and pancreatic cancers. Many research studies done in animals and human cells have shown that these types of drugs can improve how well chemotherapy works. Standard chemotherapy can be too toxic to be combined with PARP inhibitors. In this study, we use a new form of chemotherapy called PLX038 (PEGylated SN38) to see if it can be safely combined with PARP inhibitors to shrink tumors. Objective: To find a safe combination of PLX038 and rucaparib, and to see if this mix will cause tumors to shrink. Eligibility: People age 18 and older with solid tumors, small cell lung cancer (SCLC), or small cell cancer outside their lungs. Design: Participants will be screened with: Physical exam Blood tests Records of their diagnosis (or they will have a tumor biopsy). A review of their symptoms and medications. A review of their ability to perform their normal activities. Electrocardiograms, to measure the electrical activity of the heart. Computed tomography (CT) scans of the chest, abdomen, and pelvis. CT scans are a series of X-rays. Participants will get PLX038 by intravenous catheter on Day 1 of each cycle (1 cycle = 21 days). For this, a small plastic tube is put into an arm vein. They will take rucaparib twice daily by mouth on Days 3 to 19 of each cycle. They will keep a medicine diary. Participants may give a hair sample. They may have optional tumor biopsies. Screening tests are repeated throughout the study. About 30 days after treatment ends, participants will have a safety follow-up visit. They will give blood samples, talk about their health, and get a physical exam. Then they will be called or emailed every 6 months....
This is a two-part study designed to evaluate the effect of Estetrol (E4) 15 or 20 mg, or placebo on the severity and frequency of vasomotor symptoms (VMS) (Efficacy Study Part) and the safety of E4 20 mg (Endometrial and General Safety Study Part)
Current practice for diagnosing and managing PTSD relies primarily on subjective clinical assessments by clinicians as well as patient self-report. An independent, objective and neuro-physiology based method for directly assessing brain function is not available, but is much needed to improve diagnosis and management of PTSD. To address this critical need, the investigators propose to test a set of novel biomarkers which are based on measures of coherent activity among the regions of cerebral cortex during sleep. In preliminary studies on EEG acquired during sleep from Veterans with PTSD alone as well as other co-morbidities, the investigators have shown that the neuromarkers were highly sensitive/specific to the presence of PTSD, and highly sensitive to the severity of symptoms in PTSD group. The overall goal of this project is to further validate these novel neurophysiology marker in retrospective and prospective studies
Phase I/II, single center, prospective, open-label, non-controlled, non-randomized, interventional, cohort study in which low risk living donor liver transplant (LDLT) recipients who are between 1 and 3 years after transplantation and meet specific criteria (no positive crossmatch, no clinically treated rejection within 2 years preceding enrollment, permissive liver function tests (LFTs) within 30 days preceding enrollment, no prior liver biopsy showing significant fibrosis or ductopenia*) will be enrolled and will undergo a protocol liver biopsy unless they have had a permissive liver biopsy** within 90 days of anticipated immunosuppression weaning. Those patients with permissive liver biopsy** will then receive a single infusion of donor-derived DCreg and will remain on their current standard of care (SOC) immunosuppression. One week after DCreg infusion, immunosuppression weaning will be initiated. Recipients will be slowly weaned off immunosuppression. Successfully weaned participants who remain rejection-free will undergo 3 years of follow-up after the last dose of immunosuppression. They will undergo a liver biopsy at 1 yr and 3 yrs after immunosuppression withdrawal. Participants who are removed from the study protocol at any time will return to standard of care but will continue to be followed by the study team and will undergo a liver biopsy at the end of the study. * Permissive LFTs are defined as ALT, AST and total bilirubin < 2.5 times the upper limit of normal. **A permissive biopsy is based on 2016 Comprehensive Update of the Banff Working Group on Liver Allograft Pathology (the criteria detailed in Table 8, Demetris et al. 2016).
As basic and behavioral science identify new ways to improve cognition and behavior in individuals with Down syndrome (DS), the lack of rigorous outcome measures represents an important problem for interpreting findings. Null findings in clinical trials could result from insensitive outcome measures, rather than ineffectiveness of treatment. The long-term goal is to improve measurement of outcomes for children and adults with DS. Towards that goal, the investigators propose to test and refine a battery of cognitive measures that can be used in treatment studies focused on school-aged children and adults with Down syndrome. The batteries are designed to assess key domains of the DS phenotype where gaps remain in outcome measures, including attention, executive function, learning and memory, processing speed, and social cognition. The investigators will examine the psychometric properties of measures (test-retest, validity, sensitivity to change), and to evaluate differences in the psychometric properties of measures as a function of variations in participant age, gender, degree of ID, and the participants' physical health and medical comorbidities. The investigators will evaluate at least 80 children and 50 adults with Down syndrome, per site, at five time points to evaluate key domains with a diverse and novel range of methods. This proposal aims to provide a preliminary evaluation to support the enhancement of clinical outcome measures, which ultimately will increase the accuracy in documenting improvements in the lives of children and young adults with Down syndrome.
The purpose of this two part multicenter, randomized, double-blind, placebo-controlled, Phase III study is to evaluate the efficacy and safety of alpelisib compared to alpelisib matching-placebo in combination with trastuzumab and pertuzumab as maintenance treatment of patients with HER2-positive advanced breast cancer whose tumor harbors a PIK3CA mutation following induction therapy with a taxane in combination with trastuzumab and pertuzumab. Part 1 is the open-label, safety run-in part of the study, designed to confirm the recommended phase 3 dose (RP3D) dose of alpelisib in combination with trastuzumab and pertuzumab. Following Part 1, Part 2 will be initiated, which is the randomized, Phase III part of the study.
